Implementations

impl MultiAsset

pub fn new() -> Self

pub fn policy_count(&self) -> usize

pub fn insert_assets( &mut self, policy_id: &PolicyId, assets: &MapAssetNameToCoin ) -> Option<MapAssetNameToCoin>

pub fn get_assets(&self, key: &PolicyId) -> Option<MapAssetNameToCoin>

pub fn get(&self, policy_id: &PolicyId, asset: &AssetName) -> Option<Coin>

Get the value of policy_id:asset_name if it exists.

pub fn set( &mut self, policy_id: &PolicyId, asset: &AssetName, value: Coin ) -> Option<Coin>

Set the value of policy_id:asset_name to value. Returns the previous value, or None if it didn’t exist

pub fn keys(&self) -> PolicyIdList

pub fn checked_add(&self, rhs: &MultiAsset) -> Result<MultiAsset, JsError>

Adds to multiassets together, checking value bounds. Does not modify self, and instead returns the result.

pub fn checked_sub(&self, rhs: &MultiAsset) -> Result<MultiAsset, JsError>

Subtracts rhs from this multiasset. This does not modify self, and instead returns the result. If this would cause there to be fewer than 0 of a given asset an error will be returned. Use clamped_sub if you need to only try to remove assets when they exist and ignore them when they don’t.

pub fn clamped_sub(&self, rhs: &MultiAsset) -> Self

Sybtracts rhs from this multiasset. If this would cause there to be 0 or fewer of a given asset it will simply be removed entirely from the result.

Trait Implementations

impl AsRef<AssetBundle<u64>> for MultiAsset

fn as_ref(&self) -> &MultiAsset

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for MultiAsset

fn clone(&self) -> MultiAsset

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MultiAsset

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<AssetBundle<u64>> for MultiAsset

fn from(native: MultiAsset) -> Self

Converts to this type from the input type.

impl From<MultiAsset> for JsValue

fn from(value: MultiAsset) -> Self

Converts to this type from the input type.

impl FromWasmAbi for MultiAsset

type Abi = u32

The wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl Into<AssetBundle<u64>> for MultiAsset

fn into(self) -> MultiAsset

Converts this type into the (usually inferred) input type.

impl IntoWasmAbi for MultiAsset

type Abi = u32

The wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl OptionFromWasmAbi for MultiAsset

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for MultiAsset

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for MultiAsset

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, MultiAsset>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for MultiAsset

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RefMut<'static, MultiAsset>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl WasmDescribe for MultiAsset

fn describe()
